SSRF via unrestricted RequestsToolkit destinations

Published Jun 23, 2025 · Updated Jun 24, 2025

SSRF in LangChain Community before 0.0.28 allows remote authenticated users to access internal network resources through RequestsToolkit. Its request tools forward model-selected URLs through a request wrapper without restricting loopback, private-network, or metadata destinations. High-privilege access and user interaction are required; exploitation can scan ports or read local services and cloud instance metadata.
